VWINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent. No. 361,136, dated April 12, 1887.

Application filed November 23, 1886. Serial No. 210,611. (No model.)

To all whom it may concern:

Be it known that I, DANIEL Coon, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Window-Screens; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this speeication.

The special object of the invention is to improve that class of window-screens made in two sections connected by metallic clasps, so that one may slide upon the other.v

Figure 1 of the drawings is a front elevation of a screen, showing the screen open, and parts `broken away. Fig. 2 is a horizontal section on line .fr av of Fig. l; Fig. 3, a vertical section on line y y of Fig. 1; Fig. 4, "an end elevation of the stile, showing the kerf; and Fig. 5, a perspective view of the clasp.

In the drawings, A A representthe two sections of a window-screen, each provided with the net-work of wiring B, which is tacked on the rails. C are the inner and D the outer stiles, E the rails, and F the clasps.

The clasps F aremade of metal,witl1 a driveshank,f, flanged at f and a rail rest and guide, f2, with a perpendicular ange, f3. Theshank f is driven into a stile-kerf, G, which is made inthe vertex of the angle-rabbet g and in a downward direction.

In my Patent No. 315,249 the ilangef3 eX- tends in lan opposite direction from what it does in my present invention, so as to overlap and embrace the top fof rail. In practice I find this objectionable, as the impact of the window and its pressure upon this ange jams it upon the rail, so as to make it stick; hence I now reverse the iiange f, so as to make it simply a lateral guide, while the part f ",which' stood parallel to the top of rail, now comes .under the rail and forms a rest therefor, thus completely obviating the aforesaid objection.

By making the kcrf G and the angular rabbet g, I greatly facilitate the application of :0

the clasps to the screens, lessen time and labor, and secure firmly by they use of a single nail, II, for each clasp; Vhence my clasp is differently constructed and also differently applied from what has been heretofore known to the public, being let into the stile from the center, overlapping the bot/tom of rail, and rising iu what may be termed a groove7 between the webbing and the stile.

Having thus described my invention, what I claim as new, and desire to protect by Letters Patent, is

A window-scrcen clasp made of metal, with a drive-shank, f, side anged at j", and a rest, f2, having the perpendicular flange f, projecting from the rest]2 in opposite direction to the driveshankf, to adapt it to be used in the manner described.

In testimony whereof l affix my signature in presence of two witnesses.

DANIEL COOK.
